Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Dlagnosis of Sucker Rod Pumping Well mechanical type well head automatic drug feeding device, to overcome the defect existing in prior art.
Technical scheme of the present invention is: a kind of Dlagnosis of Sucker Rod Pumping Well mechanical type well head automatic drug feeding device, is characterized in that: comprise medicine storing pot and dosing pump, medicine storing pot is connected with dosing pump by flexible pipe; Wherein, medicine storing pot comprises tank body, is provided with the catheter being connected with flexible pipe in tank body, and tank body lower part is provided with discharge opeing water tap; Dosing pump comprises cylindrical shell, in cylindrical shell, be provided with plunger, plunger below is provided with spring, and plunger top is provided with plunger handle, flexible pipe by dosing pump feed liquor not the first ball-and-seat of fluid be connected with cylindrical shell, cylindrical shell below and a fluid not the second ball-and-seat of feed liquor are connected.
Described medicine storing pot bottom is provided with screen pack, and catheter and screen pack are connected as a single entity, and catheter is fixed on medicine storing pot central authorities, and catheter inlet leads directly in the liquid of screen pack below, and catheter liquid outlet is connected with flexible pipe.
On described medicine storing pot, be provided with content gauge.
Described content gauge is outside equipped with content gauge case.
The material of described medicine storing pot and dosing pump is metal, and the material of catheter is hard resin material, and the material of flexible pipe is the polymeric material with anti-corrosion function, and content gauge case is metal liquid level meter case.
Described medicine storing pot and dosing pump inner-wall spraying have anticorrosive paint.
Technique effect of the present invention is:
In the present invention, dosing pump is realized imbibition and discharge opeing by moving up and down of plunger, concrete, has two ball-and-seats on the mechanical type dosing pump housing, and wherein, the first ball-and-seat feed liquor is fluid not, and the second ball-and-seat fluid is feed liquor not.In moving up and down, dosing pump dependence sucker rod is fixed on the collision plunger handle of raming on polished rod, plunger is moved downward, the first ball-and-seat is closed under the effect of interior pressure, the second ball-and-seat is opened under the effect of interior pressure, medicine in dosing pump is discharged from the second ball-and-seat, and the spring in dosing pump is simultaneously compressed; When sucker rod moves upward, spring is realized elasticity and is recovered plunger is moved upward, in dosing pump, form negative pressure, the second ball-and-seat is closed under the effect of self gravitation and negative pressure, the first ball-and-seat is opened, medicine in medicine storing pot is inhaled into dosing pump by ball-and-seat, then sucker rod moves downward again, continues discharge opeing, thereby realizes reciprocal discharge opeing-imbibition-discharge opeing.

Fig. 1 is structural representation of the present invention.
Reference numeral is:
1-medicine storing pot, 2-content gauge case, 3-screen pack, 4-catheter, 5-dosing pump, 6-plunger, the 7-the first ball-and-seat, the 8-the second ball-and-seat, 9-spring, 10-plunger handle, 11-flexible pipe, 12-dosing mouth, 13-discharge opeing water tap, 14-content gauge.
The specific embodiment
Referring to Fig. 1, the concrete structure of a kind of Dlagnosis of Sucker Rod Pumping Well mechanical type well head automatic drug feeding device the present invention relates to is:
Comprise medicine storing pot 1 and dosing pump 5, medicine storing pot 1 is connected with dosing pump 5 by flexible pipe 11; Wherein,
Medicine storing pot 1 comprises tank body, is provided with the catheter 4 being connected with flexible pipe 11 in tank body, and tank body lower part is provided with the discharge opeing water tap 13 of discharge opeing when changing medicine and cleaning medicine storing pot 1;
Dosing pump 5 comprises cylindrical shell, in cylindrical shell, be provided with plunger 6, plunger 6 belows are provided with spring 9, and plunger 6 tops are provided with plunger handle 10, flexible pipe 11 by a feed liquor in dosing pump 5 not the first ball-and-seat 7 of fluid be connected with cylindrical shell, below cylindrical shell with a fluid not the second ball-and-seat 8 of feed liquor be connected.
Medicine storing pot 1 bottom in the present invention can be provided with to filter the screen pack 3 of impurity in medicine, to prevent the operation of some the impurity effect dosing pumps 5 in medicine storing pot 1, catheter 4 is connected as a single entity with screen pack 3, catheter 4 is fixed on medicine storing pot 1 central authorities, catheter 4 inlets lead directly in screen pack 3 below liquids, and catheter 4 liquid outlets are connected with flexible pipe 11.
On medicine storing pot 1 in the present invention, can be provided with content gauge 14, to facilitate the height that shows liquid level in medicine storing pot 1.
Outside content gauge 14 in the present invention, also can be provided with content gauge case 2.Because equipment is installed in the wild, therefore destroyed in order to prevent, outside content gauge 14, can be provided with metal liquid level meter case 2 and be protected, just only have related personnel to open, watch.
Medicine storing pot 1 in the present invention and the material of dosing pump 5 can be metal, and the material of catheter 4 can be hard resin material, and the material of flexible pipe 11 can be the polymeric material with anti-corrosion function, and content gauge case 2 can be metal liquid level meter case.
Medicine storing pot 1 in the present invention and dosing pump 5 inwalls can be coated with anticorrosive paint, to prevent that the present invention is corroded.
In the process that oil pumper suspension point moves up and down, the power of motor needing in down stroke is far smaller than the power of motor of upstroke, and some power of motor does not play a role.Therefore, the unnecessary merit of a part is transferred to above mechanical dosing pump, made dosing pump 5 rely on merit operation unnecessary in oil pumper down strokes, that realizes sucker-rod pumping well shaft medicine adds stake continuously.By designing annular liquid outlet according to actual well head, (select resin material, elastoplasticity is stronger, and corrosion resistance is strong), be fixed near the second ball-and-seat 8, make medicine flow into shaft bottom along oil-pipe external wall, medicine after mix with well liquid in shaft bottom from oil pipe output, realize the interior anticorrosion of the internal and external anti-corrosive of oil pipe and lower parts casing pipe.In addition, the dosing speed of dosing pump 5 can regulate by the length of plunger handle 10.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
